Periplaneta Americana. American cockroach's are also known as waterbugs, flying water bug and, in some areas of the South, the palmetto bug. It is the largest of the common species, growing to 1.5 inches or more in length. It is reddish-brown, with a pale brown or yellow border on the upper surface of the pronotum.
Thanks for the question. The radial artery in the wrist can be used to measure the blood pressure. But in my opinion, the brachial artery blood pressure measurement is better than radial artery for the following reasons: 1.The blood pressure at the wrist is higher for systole, lower for diastole, and about the same for mean or average pressure. The amount of difference depends on the stiffness of the arteries.ut in my opinion, the brachial artery blood pressure measurement is better than radial artery for the following reasons: 1.

The arterial blood pressure is the force causing blood to flow through the arteries, into the capillaries, then back to the heart via the veins. The left ventricle contracts (systole), ejecting blood into the aorta, creating a pressure pulse. This is the measurement known as systolic blood pressure. Part of the blood that is ejected during systole remains within the distended arteries, and rebounds during diastole (relaxation of the ventricle), creating the diastolic blood pressure.
